VEHICLE DEBBIE-LOCK CASING AND COVER.

Application filed January 17, 1923. Serial No. 613,175.

To all whom it may concern:

Be it known that I, CARL MACK, a" citizen of the United States, and resident of Long Island City, in the county of Queens and b State of New York, have invented certain new and useful Improvements in Vehicle Door-LockCasings and Covers, of which the following is a specification.

My invention relates to an improved doorlock casing and cover plate therefor and which is particularly. well adapted for use with locks for doors of automobiles :or other vehicles, steam-ships, motor boats, yachts, or houses, in places where a simpl and 5 strong lock is required. One of the objects of the invention is to eliminate the usual brazing, riveting and soldering of the various parts carried by the casing, and to that end I make the main or front plate or casing and the. various supports, lugs and guides for the locking-bolts and their operating mechanism, all in one piece of material. Another feature of my invention is the pro vision on the said casing of means for supporting or holding the escutcheon or cover plate which furnishes a suitable recess for and guards the operating lever of the boltactuating mechanism; the present practice being to secure the escutcheon plate to the door, separately from the lock casing and considerable time is thereby lost in obtaining the correct and true position of the said plate, and, moreover, the slightest shifting out of place of said plate will materially in terfere with the proper working of the lock. There are other advantages possessed by my novel construction and arrangement of the said two parts which house the locking bolts and their operating mechanism, as wil appear from the following description and the accompanying drawings illustratingmy invention and wherein; I

Figure 1, is a front elevation of the casing, with the relative location of the cover there-- on shown in dotted lines, where it overlies the same. v Figure 2, is a top-plan view of the same. Figure 3, is a side elevation of the same, the view being taken from the side having the rim for the lock-style of the door on which the lock may be mounted.

Figure 1, is a vertical sectional view of the same, the plane of the section being indicated by the line 4-4, in Fig. 1.

Figure 5, is a horizontal sectlonal view of the casing, shown asdetached and the plane of the view being on line 5-5, in Fig.

Figure 6, is an elevation of the outside of the cover shown as detached. 1

Referring to the drawings, the casing :1, has a flat plate-like body part with its outer end bent so as to form an inwardly projecting flange 2, which when the casing is mounted on the lock-styleof a door, lies upon the face of the edge of the same opposite the keeper. The flange 2, is Provided with bolt-receiving holes 3, and with screwholes 4:, for reception of attaching screws. Other screw-holes 5, are formed in the body of the casing, and also perforations 6, at the inner edge for receiving attaching members for securing a finishing frame to the front of the casing, which part 18 not shown.

Near the upper and lower ends of the 0213- ing, I cut the material thereof at 7, 7, re

spectively, in such manneras to form up therefrom inwardly projecting integral lugs 10,, and 11, the outer one 10, being slightly longer than the inner one 11. Thelugs of each pair are parallel with each'other, the outer one 10, being formed with a circular orifice 12, and the inner one with a circular orifice 13, the latter being of slightly smaller diameter than the orifice 12, which is of the same dimension as the bolt-hole 3, in the flange 2, and with whichhole the two 01'1- fices 12 and 13, are in axial alinement, thus providing practically three bearings for the reciprocating bolt which is carried therein and which has its inner end reduced in diameter to fit in the smaller orifice 13, of the bearing lug 11. While I have not shown the reciprocating bolts which are mounted in said bearing lugs, it will be noted that said bolts being reduced in diameter at their inner ends may have a shoulder thereon at such point which will take against the spring interposed between it and the outer face of bearing lugs 11, to limit the'inward movement of the'same when the bolts are retracted. In order to obtain true axial alinement of the respective openings 3, 12 and 13, I bore or cut them after the lugs are struck or bent up from the flat body part of the casing. The large perforation 14, near the outer edge of the casing is desi ed to receive a stud or member on whic is mounted the operating lever of the bolt actes ng me hanism which is not shown.

The. cover 15, is applied to the rear side of the casing 1, and is securely fastened thereto by means of a set of rivet-posts 16, the. respective ends of which pass through said cover and casing and are upset against the same, as rivets, each post having at its respective ends the shoulders 17, for engaging the adjacent face of the said casing and cover in order to space them apart. The casing is provided with suitable holes 18, and the cover with corresponding holes 1.), for receiving the rivet-posts, the space between the two said plates being for the accommodation of the various moving parts of the bolt-actuating mechanism and the operating lever. I

The cover 15, has a longer dimension in the direction of the movement of the lockwhich counter-sinking ing-bolt-s which are carried in the bearinglugs 10 and 11, but is narrower in the direction at right-angles-thereto, as indicated at- 20, 'Fig. 6, and the parallel edges of said contracted part 20, are counter-sunk by taking into the notches 21, 21, formed at the corner of each of the bearing-lugs l0, and 11, towards the center of the plate or casing, gives the cover a firm. support on the casing, in addition to the rivet-posts, and prevents any lateral shifting of the cover. The cover is also provided with a large opening 22, near its outer end corresponding in size and location with the opening 14, in the casing and for the same purpose as that described for the latter, as indicated in Figure 4, where it will be seen they register with each other.

The: inner end of the cover 15, overhangs the inner end of the casing to a considerable extent, as indicated at 23, and sufiiciently to provide a recess 24, of ample size to receive the handle end of the operating-lever of the bolt-operating mechanism, not shown. The part 23, of said cover, has its overhanging edge provided with an inwardly extending lip or ri m'25, as an enclosure for the recess, andthis is curved or bowed outwardly, while the edge of the casing lying opposite said rim, is cut away in an inward direction'to make said edge re-en'trant with respect to the casing, as indicated at 26, thus providing a suitable opening into the recess 24C, for the easy insertion of the fingers of the operator in grasping the operating lever which lies in said recess.

The cover rim 25, is notched at each end at 27, for receiving the casingl, so as to lieflush therewith, as indicated in Figs. 1 and 2, thereby afi'ording support to the finishing frame which is mounted by fasteners which take into the holes 6, on the casing, and

which'frame is not shown.

Itv will be noted that my improved lock casing and cover and the various supporting means and bearings for the pair of bolts. provide both a simple and a strong construction and that the same may be made at aconiparatively low cost from sheet steel, or duralumin or other suitable material, which can be readily cut to size and shape,

and formed up by means of suitable dies into finished form. The lugs which provide the two spaced bearings for each bolt, being integral with the body of the casing, give especial strength to the mounting of said bolts, without liability oi the bearings gettin out of alinement.

ldaving thus described my invention, what I claim and desire to secure by Letters Patent is 1. A door-lock casing and cover therefor, comprising a main front-plate I provided with'a flange formed with bolt-receiving holes and disposed so as to lie on the edge of the lock-style of the door, and having inwardly projecting lugs or ears provided with bolt--receiving bearings for the reciprocating bolts, a cover or back-plate adapted to be mounted on said main plate with a space between the two for receiving the bolts and the operating mechanisim said cover projecting beyond the inner edge of said main plate and overhanging the same at the rear edge, said cover having its overhanging end provided with an inwardly projecting rim so as to provide a recess for the reception and movement of the operating lever of the boltoperating mechanism to which access is had by the operator through the opening provided between said rim and the rear edge of said main-plate.

2. A door-lock casing and cover therefor, comprising a main front-plate provided at its outer end with a door lock-style flange and formed with inwardly projecting integral lugs or ears provided with bolt-receiving bearings arranged in axial alinement with bolt-receiving holes formed in said lock-style flange, the rear edge of said main plate being cut away inwardly and reentr'ant thereof, a cover or back plate adapted to be mounted on said main plate with aspace betweenthe two for receiving the reciprocating bolts and the operating mechanism, said cover platehaving an extension at its inner end overhanging the cut away edge of the main plate and provided with an inwardly projecting rim and providing in conjunction with said main plate a recess forthe reception and movement of the operating-lever of the bolt actuating mechanism to which access is had by the fingers of the operator through the opening constituted by the cutaway edge of said main plate and the rim of said cover. 3.- A door-lock casing and cover therefor, comprising a main front-plate provided with a door lock-style flange having bolt-receiving holes, inwardly projecting lugs arranged in pairs on said plate with the pairs suitably spaced apart and the opposing edges of the lugs of each pair being formed with notches or counter-sinks, a cover mounted on said casing and counter-sunk in said notches of the bolt-carrying lugs and overhanging the inner end of said casing to provide at such place a recess for the reception of the 0perating-lever of the bolt-operating mechanism.

4. A door-lock casing and cover therefor, comprisin a main front plate provided with a door 100 -style flange having bolt-receiving holes and bolt-bearing lugs, a cover mounted on said casing With a space between the two, the inner end of said cover overhanging the inner end of Said casing and provided at its inner edge with a rim provided at its ends With counter-sinks for receiving the adjacent edge of said casing to bring the two parts flush with each other.
